If you think you need a bachelor's degree to have a lucrative career, think again.

Yes, it's true that those with a bachelor's typically earn more than those without one — but it's certainly not always the case.

A new report by the career-guidance website CareerCast found that there are plenty of high-paying jobs — including commercial pilot and registered nurse — that don't require four years of college. They do, however, require specialized training.

"There's no question that college graduates with four-year degrees are very likely to earn almost $1 million more in compensation through the course of their careers," says Tony Lee, publisher of CareerCast. "However, for the many people who are unable to earn that degree because of the costs, financial obligations, or other reasons, it's still possible to have a very rewarding, challenging, fulfilling career that pays well.

"These jobs offer great opportunities for those job seekers," he said. "To land one of these jobs, you'll need to compensate with good old-fashioned hard work and some post-high-school training,"

CareerCast evaluated 200 professions across a variety of industries and skill levels to determine the highest-paying jobs that don't require a four-year degree. It gathered data from the U.S. Bureau of Labor Statistics, the Census Bureau, trade-association studies, and other sources.
